[54] METHODS FOR CALCULATING WATER SATURATION, WETTABILITY , AND PORE ARCHITECTURE BY MEANS OF CONVENTIONAL WELL LOGS
[57] Abstract: Methods, computer readable medium, apparatus, and program product for determining well characteristics and pore architecture for a hydrocarbon well utilizing data available from conventional/standard electronic well logs, are provided. An example of a method can include determining the value of well constants from well log data to include calculating water saturation, free water level location, wettability, and pore throat heterogeneity, and calculating pore architecture at log resolution responsive thereto. This can be accomplished, for example, by accessing well log data from a conventional well log, determining a linear regression line responsive to parameters calculated from the well log data, the linear regression line having a slope and an intercept, and determining a value of each of a plurality of well constants responsive to a value of the slope and intercept of the linear regression line.
